An approach to robotics called layered evolution and merging features from the subsumption architecture into evolutionary robotics is presented, and its advantages are discussed. This approach is used to construct a layered controller for a simulated robot that learns which light source to approach in an environment with obstacles. The evolvability and performance of layered evolution on this t...

This paper describes the implementation of a prototype locationaware tourist information system. Particular emphasis is paid to the layered architecture and the rapid configurablity.

Data mining is the automatic discovery of patterns, associations, and anomalies in data sets. Data mining requires numerically and statistically intensive queries. Our assumption is that data mining requires a specialized data management infrastructure to support the aforementioned intensive queries, but because of the sizes of the data involved, this infrastructure is layered over a hierarchic...

In recent years, a large amount of software for multitouch interfaces with various degrees of similarity has been written. In order to improve interoperability, we aim to identify the common traits of these systems and present a layered software architecture which abstracts these similarities by defining common interfaces between these layers. This provides developers with a unified view of the...

In this paper, a novel asynchronous layered interface for a high performance on-chip bus is designed in a Globally Asynchronous Locally Synchronous (GALS) style. The proposed asynchronous layered interface with distributed and modularized control units supports multiple outstanding in-order/out-of-order transactions to achieve high performance. In the layered architecture, extension of an async...

In this paper we propose a novel architecture and approach to provide accountability for Web communities that require a high-level of privacy. A two-layered privacy protection architecture is proposed, that supports (i) registration of participants and enforcement of community rules, called internal accountability, and (ii) rule-based interaction with real world organizations, called external a...

In this paper we consider techniques for designing and analysing distributed security transactions. We present a layered approach, with a highlevel security transaction layer running on top of a lower-level secure transport protocol. The secure transport protocol provides protection against dishonest outsiders, while the transaction layer can be designed to provide protection against dishonest ...

The protocols used in mobile ad-hoc networks are based on the layered architecture. The layered approach is highly rigid and strict since each layer of the architecture is only concerned about the layers immediately above it or below it. Recent wireless protocols rely on significant interactions among various layers of the network stack. A cross-layer design (CLD) introduces stack wide layer in...

High assurance security is di cult to achieve in distributed computer systems and databases because of their complexity, non-determinism and inherent heterogeneity. The practical application of formal methods is the key to high assurance security in open, distributed environments. This paper proposes the use of formal methods and a special layered architecture to achieve secure interoperation o...

In our previous work, we have proposed a new VPN architecture for enabling user-based multiply associated VPNs [1]. Almost all existing VPN technologies assume that users never simultaneously access more than a single VPN. Thus, for realizing a new VPN service allowing users to simultaneously join multiple VPNs, several fundamental mechanisms, such as dynamically changing user’s VPN association...
